Sharp Energy Solutions Business
A track record of over 60 years
In 1959, Sharp became the first company in the world to embark on research and development into solar cell devices. Sharp's solar products are at work in many areas: on homes, in extreme environments such as lighthouses and artificial satellites, and in megawatt-scale solar power plants around the world. Sharp's track record of over half a century has earned it a solid reputation in the world of solar.

Strict quality testing and long-term durability
Sharp solar panels—vital to generating power—undergo a range of proprietary Sharp in-house tests that are much stricter than the equivalent standards under IEC*1, JIS*2, and other institutions.
Such testing enables Sharp panels to last longer, a crucial factor in the power generation business.
- *1 Standards stipulated by the International Electrotechnical Commission (IEC), an international organization that prepares and publishes international standards for electrical, electronic, and related technologies. The IEC standards here refer to IEC 61215 (ed. 2) for performance and reliability and IEC 61730-2 (ed. 1) for safety.
- *2 Japanese Industrial Standards (JIS). JIS standards are the Japanese national standards established for the standardization and measurement methods of industrial products in Japan.
Quality testing based on strict proprietary Sharp standards
High temperature and humidity test, humidity freeze test, PID (potential induced degradation) test
Mechanical load test
We put our over 60 years of expertise in solar business into product evaluation to ensure we can provide high-quality products that give long-term, stable operation even under extreme conditions, be it wind, rain, high temperature and humidity, accumulated snow, frost, or salt air.
